SerialToNeopixel
Takes serial input with led number and rgb values and sets rgb of neopixels accordingly
The input should match the following format:
P6:255,255,255
P7:0,0,255
The first line sets LED number 6 to be bright white and the second line sets LED number 7 to be bright blue.
Keep in mind:
-that neopixel library is needed! (found at https://github.com/adafruit/Adafruit_NeoPixel)
-that pin numbers are subject to change
-that number of neopixels is subject to change
